Bougies as Aid for Endotracheal Intubation Via Video Laryngoscopy During Continuous Chest Compressions
Study Details
Study Description
Brief Summary
The goal of this clinical trials is to analyze the effects of using bougies as adjuncts on the performance of endotracheal intubation via video laryngoscopy during cardiopulmonary resuscitation in anesthesia residents. The main question it aims to answer is whether bougie use has a significant effect on first-attempt failure of endotracheal intubation via video laryngoscopy during continuous chest compressions. Participants will perform endotracheal intubation via video laryngoscopy by four methods in a randomized order in a simulated cardiopulmonary resuscitation scenario on a manikin. The four methods are endotracheal intubations assisted by a railroaded bougie, assisted by a preloaded bougie, assisted by a stylet, and with no assistance. Researchers will compare the first-attempt failure rate of the four methods to see if a railroaded bougie method has a significant different first-attempt failure from that of the other three methods.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Railroaded bougie An endotracheal tube is loaded onto a bougie posterior to the placement of the bougie into the trachea. |
Device: Railroaded bougie
Residents expose the glottis by a video laryngoscope and place the tip of bougie through the vocal cords. Then, an assistant loads an endotracheal tube on the free end of the bougie. Residents advance the endotracheal tube over the bougie and withdraw the bougie.
|
| Other: Preloaded bougie An endotracheal tube is loaded onto a bougie prior to initiating laryngoscopy. |
Device: Preloaded bougie
Residents expose the glottis by a video laryngoscope and perform the endotracheal intubation using a bougie with a preloaded endotracheal tube while an assistant secures the free end of the bougie. Residents withdraw the bougie when the endotracheal tube reaches an appropriate depth.
|
| Active Comparator: Stylet A stylet is placed within an endotracheal tube prior to initiating laryngoscopy. |
Device: Stylet
Residents expose the glottis by a video laryngoscope and perform the endotracheal intubation with the assistance of a stylet. An assistant withdraws the stylet when the tip of the endotracheal tube passes through the vocal cords. Then residents place the endotracheal tube to an appropriate depth.
|
| No Intervention: Naked endotracheal tube Residents expose the glottis by a video laryngoscope and perform the endotracheal intubation without assistance of stylet or bougie. |
Outcome Measures
Primary Outcome Measures
- Failure on the first attempt [At the completion of the intubation]
An attempt is terminated and defined as a failure when a resident tries for one minute but is still unable to start ventilation, or when a resident feels unable to succeed and decides to give up, or when a resident withdraws a laryngoscope blade, a bougie, or a tube out of the month after the initial insertion. This outcome will be measured based on videos of endotracheal intubation procedures recorded by a camera placed on the right side of the manikin.
Secondary Outcome Measures
- Failure on two attempts [At the completion of the intubation]
If the first attempt of a method fails, the resident will be given a second opportunity of the same method. This outcome will be measured based on videos of endotracheal intubation procedures recorded by a camera placed on the right side of the manikin.
- Duration of the first attempt [At the completion of the intubation]
The time elapsed between the insertion of a laryngoscope blade into the month and either the start of ventilation in a successful attempt or the termination of a failed attempt. This outcome will be measured based on videos of endotracheal intubation procedures recorded by a camera placed on the right side of the manikin.
- Overall intubation duration [At the completion of the intubation]
Duration of the first attempt if it succeeds or the sum of the duration of both attempts if the first attempt fails. This outcome will be measured based on videos of endotracheal intubation procedures recorded by a camera placed on the right side of the manikin.
- Self-reported intubation difficulty [At the completion of the intubation]
0-10 ranking scale with 0 representing "the easiest" and 10 "the most difficult" rated by the residents.
